Patent FR-2227208-A1 (FR)
Title: Textile machinery broken thread indicator - protects operator by switching off machinery and gives warning
IPC: B65H63/032
Filed: 1973-04-25
Abstract: Electronic broken thread indicator is for textile machinery or similar. Contacts closed in the event of a breakage complete a lever voltage circuit using a semi-conductor; so illuminating a warning lamp. A more complicated form uses a semi-conductor circuit to lock in the electrical supply, either single or three-phase, to the machinery. Closing the contacts activates one semi-conductor, illuminating a warning lamp and at the same time breaking the circuit ensuring the supply, so stopping the machinery. In both instances the circuits use low voltage obtained by transformer from the main supply.

The bores of the half shells are provided with a number of parallel sharp edged ridges (6) which exert a firm grip on the tubes (2). The ridges of each half are disposed at an angle to the end flanges and the junction of the ridges of each half forms an obtuse angle. The idea can be adapted to secure a branch pipe to the main pipe.
Patent FR-2246215-A1 (FR)
Title: Cultivator tine and cutting tip assembly - tip is positioned for bolting by a projecting pin on the tine
IPC: A01B35/26
Filed: 1973-10-05
Abstract: Simplified mounting gives fast and easy removal of the tips which are reversible. The tine (1) has two holes (2, 3) spaced one above the other, near the free end. The wear tip (4) also has two holes (5, 6) which are spaced centrally to match those in the tine and countersunk. A dowel pin (7) welded (8) in the bottom hole of the tine accurately locates the tip. In the upper hole, a bolt and nut are used to lock the tip onto the tine. The dowel pin does not protrude above the tip surface and is therefore protected against damage. The tip is reversed by changing the positions of the countersunk holes.

Title: Hydraulic pressure control device using linked PTFE bellows - for remote control of pressures in cells at extreme temps.
Inventor: TREMBLAY DANIEL
IPC: G05D16/06
Filed: 1975-06-10
Abstract: Equipment for maintaining the pressure on a liq. maintained under monophase conditions using elevated pressures at high temps., when the liq. in the hot cell is connected via capillary tubes to ancillary devices for monitoring the pressure and adjusting the col. of the system to compensate for any effects tending to vary the pressure. The volume compensation device incorporate a pair of linked bellows filled with an incompressible fluid, one bellows being in a chamber on line with the pressurised capillary, the other bellows being surrounded by a reservoir for an independently adjustable hydraulic pressure source which can be used to vary the relative volumes of the two linked bellows. Esp. suitable for equipment conducting experiments at critical point cell conditions, e.g. 374 degrees C/221 bar pressure for water. The pressure compensation device is remote from the temps. in the cell, allowing use of pressure compensation bellows made of materials such as PTFE which can perform well, but not at the (high or low) temps. maintained in the cell. Heat transfer between the cell and the pressure control system is inhibited by use of capillary tubing for the pressure line link.

Patent FR-2298135-A1 (FR)
Inventor: PARTON KENNETH CHARLES
IPC: H02H9/02
Filed: 1976-01-19
Abstract: In order to reduce the energy losses, at least two saturable inductor devices (12, 13) are provided in the current-limiting unit for each phase of the AC device. Each inductor device has an AC winding (10A, 10B, 10C; 11A, 11B, 11C) and a superconductive DC premagnetising winding (20, 36) which saturates the inductor core (12A; 12B; 12C; 13A; 13B; 13C) in such a manner that the latter remains saturated even when the AC device is on full load. The AC windings (10A, 10B, 10C; 11A, 11B, 11C) act per phase such that, at full load, a change in the saturation level in one of the inductor cores (12A; 12B; 12C; 13A; 13B; 13C) with respect to the saturation level produced just by the premagnetising winding (20, 36) is associated with an opposing change in the saturation level in the other inductor core (12A; 12B; 12C; 13A; 13B; 13C) of the same phase. The current limiting takes place when, in each half-cycle, one or other of the inductor cores (12A; 12B; 12C; 13A; 13B; 13C) is forced out of its saturation state. The unit is particularly suitable for power transmission between two power AC devices.
